BOTTLE-CAPPNG DEVICE.

Application filed October 4, 199.1. Serial No, 505,278.

to devices tor applying the caps, such as 1 metal caps required to be bent tol place, to

the mouths of bottles to seal them.

lMy primary object is to provide a novel, simple and inexpensive construction oi' bottle capping device which -will be highlyy effective in operation and durable, and which may be folded into relatively compact con.- dition inore particularly for transportation or storage.

Referring to the accompanying drawing: Figure 1 is a perspective view oi iny improved' construction. Figure 2 is an en laiged broken view in vertical elevation koiI the cap-engaging portion ot the device. Figure 8 is anenlarged section taken at the line 3 8 on Fig. 1 and viewed in the direction of the arrows; and Figure 41, an enlarget broken view in vertical side elevation oi the upper portion oit the device. The device as shown comprises a baseplate 5 which may contain openings represented at 6 Jfor receiving screws to-screw the base-plate in place on a support, this base-plate being formed at its opposite edges toward its rear end, with upright plate portions 7 of angle shape in plan section, to ati'ord the inwardly-extending flanges 8 at their rear edges, the rear edge of the baseplate 5 being termed with an upwardly-extending plate portion 9 preferably extending entirely across the plate 5 and in direct line beneath, and preferably in contact with, the lower edges o1' the plate portions 8 as shown. rllhe base member 5 is preferably ina-e e from a single sheetJ of metal of the desired gauge, the metall being cut into a blank and the upright angular plate portions 7 and the plate portion 6 bent therefrom into the position shown and described, livotally connected at its lower end with'theu plate 5 is arachequipped upright 10, this upright being preferably formed of two similar bar portions 11 the upper ends of' which, at one edge of the upright, being formed with the rack teeth 12. rihe parts of the bars 11 in which the rack teeth are formed are pret if desireth:

erably straight and flat and lit Vlatwise together, in which condition they .are rigidly secured as by rivets 18.y The lower ends of the bars 11 ybelow the rack-portions are di-y vergent, asrepresented, and terminate in the parallel spaced portions 14 which extend at the inner sides ont the plate portions 7 and within the angles provided by the latter, these bars being'pivotallyI connected with the plate portions 7 as through the medium of the rivets represented at 15 and extending through these bars and plate portions, whereby the uprightlO is adapted to be swung upon the plate portion 5 from they vertical, operating, `position represented, in which the upright 10 extends substantially at a right angle to the body of the base 5, to a position in which parallelsthis portion of the base. Locking means for releasably securing 'the upright 10 in the vertical position shown are provided, these locking means comprising a bar 16 shown as, and by prefn erence, of rectangular shape in cross-section, which extends at lits opposite ends through vertical elongated slots 17 in the bar 11 and is movable up and down therein, the eX- tremities of the bar 16 being adapted to en-r ter grooves 18, in the upper edges of the plate-portions 7, the groove 18 for one only of lthese plate-portions being shown. The bar 16 is held against lengthwise movement by cotter pins 19 extending crosswise through openings therein adjacent the inner sides of the bars 11, one only of these pins being shown. In the operating position'oft parts shown in Fig. 1, the bar 16 is in position for locking the upright 10 in vertical position, the ends of the bar 16 being located within the slots 18. When it is desired toy swing the rack member 10 to the position in which is parallels the body portion et the base 5, the operator lifts the bar 16 to withdraw its ends from the slots 18 and thereupon swings the upright 10 on the pivots 15 to the position last referred to. The forward edges 20 oi the plate portions 'Y are so formed, as :tor example as shown,

' that ,inthe swinging'oi the rack-portion 10 from a position in which it extends parallel with the body' ot the base 5 to vertical position, the bar 18 will ride freely upon the iront edges of the plate-portions 7 and as soon as the raclrmember. 10fhas assumed ver tical position will drop into the slots 18 and thuslock the unrivht 10 in o erative osition. f

CII

portion are i'irmly secured together.

Surrounding the rack-portion 12 of the upright 10 and movable up and down thereon, is a head 21 in the form oi' a slide preferably formed from a singlesheet of metal and bent to provide an opening 22 therethrough at which the head slides upon the upright 10, the metal of this head being deflected inwardly at opposite sides at the upper end ol the head, as represented at 23, at which the parts are secured as by the rivet 24, the metal at they lower edge of the head 21 being slit at one side and deflected inwardly as represented at 25, at which portion it is riveted, as indicated at 2G, to the opposite side of the head 21, whereby the head 21 is positively guided at its upper and lower edges on the raclr 12 to permit of the movement of the head vertically on the rack without wabbling. The side portions ot' the head, represented at 27, are spaced apart between the portions 23 and 25, yand located therebetween is a lever 28 pivoted to these side plates as indicated at 29. The inner end or this lever is formed with a segn'iental gear portion 30 which meshes with the raclr 12 and operates, when the lever 28 is rotated in one direction on its pivot 29, to fonce the head 21 downwardly, and when rotated in the opposite direction to lift the head. The lever 2S is preferably formed of two similar plates 31 fitting flatwise together, each having the gear teeth 30 referred to, these plates being connected together at their outer ends by rivets 32 which also serve to secure a handle portion 33 to these plates. The handle portion 33 is preferably made from a single sheet ot metal bent into the form shown to provide the opposite side portions 34, one only ot which is shown, with a curved upper plate portion 35, the outer extremity of the handle portion 34 being also curved downwardly, as represented at 36, the portion 33 preferably tapering in width from its end 36 toward its opposite end, its wider end being preferably about twice the width of its opposite end, at the top of portion 33. The side portions 3a extend rearwardly beyond the curved upper portion 35 of the handle, as shown,`and the rivets 32 extend through these extensions of the side portions, whereby the plates 28 and the handle The forming, or die, member provided for forcing the cap into sealing position at the mouth of a bottle whichk would be positioned on the horizontal portion ot the base plate 5, is represented at 37 and vis shown oit a shape commonly employed. It is in the 'form of an inverted cup member riveted at its upper surface, as indicated at 38, to outwardly-eitending lugs 39 on, and `integral with, the lower edges of the plates 27, with a heavy metal disk 332L interposed between the lugs 39 and the 'cup 37, the cup being shown as containing a block 10 of elastic material, as for example rubber, acting as a cushion.

It will be understood that in the operation of bottle-capping devices the rackequipped upright is subjected to relatively great stress tending to swing it to the left in Fig. 1. In my improved construction this force is counteracted by the interlocking of the plates 11 with the plate portions 3 which in turnabut at their lower edges against the plate portion 9. I am thus enabled to employ relatively light metal for the base member of the device while maintaining the desired rigidity of the parts. rilhere is also a tendency of the base-plate 5 to buckle, but this tendency is resisted in a manner to prevent the plate from buckling, by the provision of the plate-portion 9.

rl`he construction of the handle-portion 34 is also of advantage in a construction of this character, as it may be made very economically and still present the desired rigidity, and its rounded upper surface avoids hurting the hand of the operator.

rlhe forming of the lever 28 as shown and described is desirable as it permits the structure to be made very economically and also causes the lever 28l to present an offset p0rtion at eachside as at 33l1 which in the downward sim/'inging of the lever 28 engages the inclined surfaces 33b of the head 21, thereby affording a positive stop for the lever and preventing the latter from resting on, or passing against, the dome of cup 37 which avoids twisting or dislocatingv the latter. However, ii" desired, the lever may be made as integral structure and in such case m improvement in the handle portion of the structure may be incorporated.

The feature of providing the lugs 39 integral with the head 21 is of' advantage as the angle-construction thus provided serves to greatly strengthen the structure of the head, and when combined with the attachment of the cup 37 thereto provides rigid and secure fastening for the sides of the head. Furthermore, in the capping of a bottle pressure is exerted on the cup 37 by the bottlemouth and cap which has a tendency to twist or distort the head 21 and which if it occurs prevents the cap from being properly applied to the bottle. provision of the lugs 39 to extend parallel with the bottom of the cap 37 and at a right angle to the direction of thrust on the cup in the capping operation, minimizes twisting or distorting of the cup. Possibility of such distorting or twisting occurring is still further provided against by the provision of the disk 38a.

While I have illustrated and described a particular construction embodying my invention, I do not wish to be understood as intending to limit it thereto as the same The may be variously modiied and altered Without departing from the spirit of my invention.
